acrosome reaction

Term Information

Accession
GO:0007340
Name
acrosome reaction
Ontology
biological_process
Synonyms
None
Alternate IDs
None
Definition
The discharge, by sperm, of a single, anterior secretory granule following the sperm's attachment to the zona pellucida of the oocyte. The process begins with the fusion of the outer acrosomal membrane with the sperm plasma membrane and ends with the exocytosis of the acrosomal contents into the zona pellucida. Source: GOC:dph, PMID:11175768, PMID:3886029, PMID:21042299
Comment
If the release of the acrosome content occurs before the sperm reaches the zona pellucida, consider using premature acrosome loss.
